Well, I’m going to go against the tide and say I wouldn’t shy away from a 2000 Johnson at all.
2 strokes are incredibly time-tested designs that have reliability and longevity that is nothing short of astonishing if you really think about it. I ran a 1984 Johnson 25 HP for hundreds and hundreds of hours and did nothing more to it than change spark plugs and lower unit lube. A properly maintained 2 stroke can do thousands of hours with an absolute minimum amount of maintenance.
Simplicity, ease of maintenance, and reparability are key advantages that a 2 stroke can offer. Keep in mind, by the 2000s, many 2 strokes that were in the major manufacturer’s lineups has been manufactured for decades using similar designs or in some cases virtually the same designs.
While all the fancy EFI 4 strokes have benefits, because they are relatively new, what many guys HAVEN’T experienced yet is the downside. What happens when the age-related failures start to kick in. That fuel pump, fuel injectors, etc on an EFI aren’t going to last forever. People who think the all-singing-all-dancing 4 strokes are invincible are going to be getting a surprise in the coming years when all these intricate and very expensive parts start to fail. No mechanical object is maintenance free and breakdown proof forever.
I think you have to look at your real needs and budget. Yes, a carb 2 stroke is thirsty. How much this matters to you depends on where you plan to take the boat, the size of the onboard tank, etc. In my case, the extra gas money never came close to justifying dropping thousands more on a 4 stroke.
Horses for courses. No doubt a 4 stroke is nice if you budget allows for it, but 2 stokes worked for decades and will continue to get the job done. Better to be on the water puffing a little extra smoke than sitting at home wishing you had a 4 stroke.
